摘要
A series of novel pyrrolo[2,3-b]pyridine derivatives bearing 1,2,3-triazole moiety were designed, synthesized, and evaluated for their c-Met kinase inhibitory activities and antiproliferative activities against 4 cancer cell lines (HT-29, A549, MCF-7, and PC-3) in vitro. Most compounds showed moderate to excellent potency, with the most promising analog 34 showing a c-Met IC50 value of 1.68 nM. Structure-activity relationship studies indicated that electron-withdrawing groups (X = CF3, R-1 = F, R-2 = 4-F) were required to decrease the higher electron density on the 5-atom linker to a proper degree to improve the inhibitory activity.
